I have checked your profile and watched some of your recent chess games, I found out that you are playing long time control and you are winning almost all of your chess games, this is a powerful come back.

Let’s watch one of your recent chess game below:
In above game, you outperformed your opponent slowly but surely and that’s called a strategy, at your level, its impossible to play like this but you are playing it, and that’s good thing.
I have created a study plan for you for getting 1800 rating.
Study Plan to Reach 1800 Rating
1. Openings
Focus on mastering 3-4 openings deeply rather than playing too many different lines. This will give you confidence and reduce mistakes.
with White:
Against 1…e5: Study the Italian Game (e.g., 1. e4 e5 2. Nf3 Nc6 3. Bc4) or Ruy-Lopez.
Against 1…c5: Study Anti-Sicilian systems like 2. Nc3 or the Open Sicilian.
Against other defenses: Prepare a basic repertoire against the Caro-Kann and French.
with Black:
Against 1. e4: Master the Sicilian Defense (e.g., Najdorf or Classical) or stick with a solid 1…e5 repertoire like the Petrov Defense.
Against 1. d4: Study the Nimzo-Indian Defense or the Queen’s Gambit Declined.
Training: Learn common traps of your opening’s traps.
Use Chessable or Lichess Opening Explorer to learn key lines and Spend 15-20 minutes daily on opening theory.
2. Middlegame Strategy
There are two things you need to improve, one is pawn structures and second is tactical motifs.
Pawn Structures:
Study isolated pawns, doubled pawns, and pawn majorities. Learn plans associated with each structure.
Piece Activity: Ensure every piece contributes to your position, and avoid passivity.
Tactical Motifs: Keep sharpening your tactical vision by solving 20 chess puzzles daily with theme in mind.
Training: Use books like “My System” by Aron Nimzowitsch to understand pawn play and piece coordination. Solve 5-10 thematic positional puzzles daily, focusing on concepts like outposts, weak pawns, and open files. Analyze classic games by players like Capablanca to understand strategic planning.
4. Endgame
To consistently beat 1800-rated opponents, you need mastery of basic and intermediate endgames.
King and pawn endgames: Opposition, triangulation, and breakthrough techniques.
Rook endgames: Lucena and Philidor positions.
Minor piece endgames: Handling bishops and knights in simplified positions.
Training:
Work through “Silman’s Complete Endgame Course” (chapters relevant for 1400–1800). Spend 20 minutes every other day solving endgame positions. Practice practical endgames on Lichess Endgame Trainer or chessable.com.
